1.1 Oral contraception without progestins (NOPANTE)*

On May 30, 2023 the leading scientific journal dealing with basic and clinical breast cancer research “Breast Cancer Research (BCR)” published the Perspective Review paper “Progesterone from ovulatory menstrual cycles is an important cause of breast cancer” by Herjan J.T. Coelingh Bennink, Iman J. Schultz, Marcus Schmidt, V. Craig Jordan, Paula Briggs, Jan F.M. Egberts, Kristina Gemzell-Danielsson, Ludwig Kiesel, Kirsten Kluivers, Jan Krijgh, Tommaso Simoncini, Frank Z. Stanczyk and Robert D. Langer.

The most important message of this narrative review paper is that progesterone from normal menstrual cycles causes most BCs, whereas estrogens and androgens may stimulate existing hormone receptor positive BC, but do not cause BC. Four authors of this paper are related to Pantarhei (HCB, IJS, JFME and JK) and the other nine authors are experts in the field of Reproductive Endocrinology and Oncology, supporting this rather thought-provoking paper, that will hopefully lead to a reappraisal and a turnaround of the medical view and opinion on the cause of breast cancer and change the negative perception of estrogens.
